IMPORTANTSAFETYNOTICE
Manyelectricalidentifythesepartsandmechanicalpartsinthischassishavespecial
safety-related characteristics! Inthe SchematicDiagramand Replacement PartsList.
It isessentialthatthesespecialsafetypartsshouldbe replacedwiththesamecomponents
asrecommended inthismanualtoprevent X-RADIATION, Shock, Fire, orotherHazards.
Donot modifythe originaldesign without permission of themanufacturer.
General Guidance
AnIsolation Transformershouldalways be used during theservicing ofareceiverwhose
chassisisnotisolatedfromthe ACpowerline.Useatransformerofadequatepowerrating
asthisprotectsthe technician fromaccidentsthatmightresultinpersonalinjurycaused by
electricalshocks.
It willalsoprotectthe receiverand itscomponentsfrombeing damaged byaccidentalshorts
of the circuitrythat might be inadvertentlyintroduced during theserviceoperation.
If anyfuse(orFusibleResistor)inthisTVreceiverisblown, replaceit withaspecified one.
Whenreplacingahighwattage resistor(Oxide MetalFilmResistor,over1W),keep the
resistor10mm awayfromPCB.
Keep wiresawayfromhigh voltageorhigh temperatureparts.
Due tothe highvacuumand large surfacearea ofthe picturetube,extremecareshouldbe
taken inhandling the PictureTube. Donotlift the PictureTube byitsNeck.
X-RAYRadiation
Warning:
The sourceofX-RAYRADIATIONinthisTVreceiveristhe HighVoltage Sectionandthe
PictureTube.
Forcontinued X-RAYRADIATIONprotection,the replacementtube mustbe ofthe same
type asspecifiedintheReplacement PartsList.
Beforereturningthe receivertothecustomer,
Always performan ACleakage currentcheckon theexposedmetallicpartsofthe cabinet,
suchasantennas,terminals,etc.,tomakesurethatthesetissafetooperatewithoutany

General ServicingPrecautions
1.Always unplug the receiverACpowercordfromthe ACpowersourcebefore:
a.Removingorreinstallinganycomponent, circuitboardmoduleoranyotherassembly
of the receiver.
b.Disconnecting orreconnecting anyreceiverelectricalplugorotherelectrical
connection.
c.Connecting atest substituteinparallelwithanelectrolyticcapacitorinthe receiver.
CAUTION: Awrong substitutionpartorincorrectinstallation polarityofelectrolytic
capacitorsmayresultinan explosion hazard.
d.Discharging the picturetubeanode.
2.Testhighvoltage onlybymeasuringitwithan appropriatehighvoltage meterorother
voltage-measuringdevice(DVM,FETVOM,etc.)equippedwithasuitablehighvoltage
probe. Donot test high voltage by “drawinganarc”.
3.Discharge the picturetube anode onlyby(a)firstconnecting one end ofan insulated clip
leadtothe degaussingorkine aquadaggrounding systemshieldatthe pointwherethe
picturetube socketgroundlead isconnected,and then (b)touchthe otherendofthe

CAUTION: Workquicklytoavoidoverheating the circuit boardprintedfoil.
6.Usethe following unsoldering technique
a.Allowthe solderingiron tiptoreachnormaltemperature. (500o Fto600o F)
b.First, holdthe soldering irontipand solderthestrand against the componentlead until
the soldermelts.
c.Quicklymovethe soldering iron tiptothejunction ofthe componentleadandthe
printed circuitfoil,and holditthereonlyuntil the solderflowsontoand around both
the component lead andthe foil.
CAUTION: Workquicklytoavoidoverheating the circuit boardprintedfoil.
d.Closelyinspectthesolderareaandremoveanyexcess orsplashedsolderwitha
small wire-bristlebrush.
Remove/Replacement
Somechassiscircuitboardshaveslotted holes(oblong)through whichthe ICleadsare
inserted and then bentflatagainstthecircuitfoil.When holesareofslotted type,the
followingtechnique shouldbe used toremoveand replacethe IC.When working withboards
usingthe familiarroundhole, usethe standardtechniqueasoutlined.
Removal

Removal/Replacement
1.Clipeachfuseorresistorlead at top of the circuit boardhollowstake.
2.Securelycrimpthe leadsofreplacement component around notchat staketop.
3.Solderthe connections
CAUTION: Maintainoriginalspacingbetween the replaced componentand adjacent
componentsand the circuitboardtopreventexcessivecomponent temperatures.
CircuitBoardFoil Repair
Excessiveheatappliedtothe copperfoil ofanyprinted circuitboardwill weaken the
adhesivethatbondsfoiltothe circuitboardcausing the foiltoseparatefromor “lift-off”the
